Abstract:
Thirty two Sudanese local cows (Kenana and Butana) were kept for study under the same conditions in zero grazing. Sixteen cows from each breed at the third milking season and the fourth month post-partum were separated into four groups. Each group included four Kenana and four Butana separated from each other, fed in the same ration. The average daily milk yield was 14 and 12 lbs for kenana and Butana, respectively. Before the trial and after the trial group one let as control group and milked once a day, group two twice a day, group three, three times a day and group four, four times a day. The result was 14, 18, 23 and 25 Lbs for the groups, respectively. So far the yield of Butana was 12, 16, 19 and 22, respectively. From the sequences kenana seems to give better performance than Butana although milking twice a day appeared to be significant and benefited and better than the frequencies of the other groups.
